Hello again I've discovered one more problem. Commented code bellow doesn't compile, because of private inheritance. I don't think that it is a bug, but just limitation of the current implementation. But it limits use of C++, so, if I want to use boost::serialization library I don't allowed to use private inheritance. I don't think that it is very good :) Anyway, if it can not be fixed easily, this limitation should be explicitly stated in docs, or in library's code, that compiler error points to.
